A chemical bond to form in a chemical compound must be formed by two or more atoms attracted to one another.
Analyzing the proteins of the Racoons and lesser pandas, there will be huge similarities with minor modifications.
These species will be very closely related.
<h3><u>Explanation:</u></h3>
The evolutionary background of the species are mainly studied based on the similarities of the nucleotide sequences and proteins. While studying the Lesser pandas and Racoons, there was a huge similarities in then based on their structures, and on their protein composition. The nucleotide sequences also showed huge similarities which also points that they have developed from same ancestor. This is why they are very closely related with each other by means of evolution.
Pathogen 3 will most likely be a virus with the features seen in the table.
<h3>
What is a Pathogen?</h3>
